In which of the following pair both the species have s p^3 hybridization?

Step-by-step solution

Key concept - Hybridization (Z= 1 2 ( No. of valence e⁻ of central atom + Monovalent atom + charge ) ) ( aligned & (1) H ₂ ~S , B ~F ₃ & H ₂ ~S = 1 2 (8+2)=4 S p^3 & B F₃= 1 2 (3+3)=3 s p^2 aligned ) ( aligned (2) SiF ₄ & = 1 2 (4+4)=4 s p^3 B C H₂ & = 1 2 (2+2)=2 Sp aligned ) ( aligned (3) & N f₃= 1 2 (5+3)=4 s p^3 & H₂ O= 1 2 (6+2)=4 S p^3 aligned ) ( aligned (4) & N F₃ = & 1 2 (5+3)=4 s p^3 & B F₃= 1 2 aligned )
